Title: Production of vibration damping steel pipe
Inventor: UOZUMI KAZUHIRO
IPC: B21C37/06
Filed: 1990-07-30
Abstract: PURPOSE:To obtain the vibration damping steel pipe having the effect equiv. to the effect of a vibration damping steel by fitting an inside pipe coated with a thermoplastic resin to an outside pipe to form a composite pipe, then subjecting the pipe to diametral reduction working after or during heating, thereby producing the vibration damping steel pipe. CONSTITUTION:After both the inside pipe 1 and the outside pipe 2 are subjected to pointing, the surfaces thereof are treated by subjecting the pipes to a phosphoric acid treatment in a pretreating stage A. The inside diameter of the outside pipe 2 needs to be larger than the outside diameter of the inside pipe 1 at this time. The surface of the inside pipe 1 is uniformly coated with the liquid thermoplastic resin at a prescribed thickness while the inside pipe is kept rotated in a resin painting stage B. The inside pipe 1 coated with the thermoplastic resin is charged into a drying furnace or the like to evaporate the solvent in a drying stage C and thereafter, the inside pipe 1 is fitted into the outside pipe 2 in a combining stage D, by which the composite pipe is formed. The pipe is heated up to the melting temp. of the resin to half melt the resin in a heating stage E. The diameter of the pipe is reduced by dies, etc., by which the inside pipe 1 is adhered to the outside pipe 2 in a diametral reducing stage F. The vibration damping steel pipe is thus produced.

Title: Optical demultiplexer
Inventor: AJISAWA AKIRA
IPC: G02F3/00
Filed: 1990-07-27
Abstract: PURPOSE:To form the above optical demultiplexer which is smaller in size, is more highly integrated and operates on lower voltages by integrating optical branching circuits, optical gate switches formed by using the electricity absorbing effect of semiconductors and optical amplifiers. CONSTITUTION:This optical demultiplexer is constituted by integrating 1Xn optical branching circuits 14, optical waveguides of a pin structure optically coupled to respective branching destinations, i.e., the optical gate switches 15 formed by using the electricity absorbing effect of the semiconductors, further the optical amplifiers 16 optically coupled to that. The optical gate switches 15 as small as 200mum element length and have excellent characteristics of >=15dB extinction ratio at about 3V voltage and, therefore, the optical demultiplexer which operates on the sufficiently low voltage is obtd. Further, the series connection of the optical gate switches 15 is obviated even if the number of the optical branches is structurally increased. Since the light power attenuated by the optical branching is sufficiently made up by the optical amplifiers 16, the expansion of the number of the branches is extremely easy. The optical demultiplexer which is smaller in size, is more highly integrated and operates on the lower voltages is obtd. in this way.

Title: Cylinder pump
Inventor: ITO YOSHIO
IPC: A61M5/145
Filed: 1988-08-10
Abstract: PURPOSE:To stop the pump operation in a short time in the overload state with a simple structure by installing an overload detecting mechanism which detects the overload state of a slider according to the load generated on a pipe shaft, accompanied with the stop of the slider, and a drive stop mechanism which stops the drive of a driving source according to the result of the detection. CONSTITUTION:When the aqueous solution in a cylinder 3 is exhausted, and a slider 7 contacts an upper case 2a, an operation stop mechanism operates. Since a driving motor 20 is in revolution, a feed screw 22 shifts, and also a clutch shaft 29 connected with the feed screw 22 through a feed nut 23 tends to move similarly. Because the slider 7 is in stop state, the load is transmitted to a pipe shaft 26 which does not move similarly, and further transmitted to an overload spring 30 connected with the pipe shaft 26. A detecting plate 31 is gradually pulled out by the overload spring 30 which is excessively loaded, and the pulled-out distance is detected by a reflection type photosensor 33. When the pulled-out distance becomes over a prescribed value, a stop signal is transmitted from the reflection type photosensor 33 to the driving motor 20, which stops.

Title: Finish annealing method of directional electrical sheet
Inventor: KAWABATA TOSHIMI
IPC: C21D9/52
Filed: 1982-11-16
Abstract: PURPOSE:To obtain a directional electrical sheet which is less strained in the side edge of a coil in finish annealing by coiling a steel sheet while applying an annealing releasing agent on the surface thereof in a larger amt. on one side prior to finish annealing and placing the coil in an annealing base plate in such a way that said one side contacts with the base plate. CONSTITUTION:A hot rolled directional sheet contg. up to 4.0% Si is subjected to >=2 times of cold rolling including intermediate annealing then to decarburization annealing. Such cold rolled steel sheet is coiled while an annealing releasing agent is coated more on one side in the width dirction of said sheet than on the rest to increase coiling tension of the one side. The coil 1 is placed perpendicularly on an annealing base plate 11 in such a way that the one side 1-1 coated with the annealing releasing agent in the larger amt. contacts with said plate, and thereafter the coil is subjected to finish annealing. Since the one side of the coil 1 is tightly wound according to such method, the generation of strain is suppressed and since the remaining part is wound relatively loosely, the contact with a gaseous atmosphere is smoothly effected and a good insulation film is formed.

IPC: G01R25/00
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To measure phase difference with high precision by executing correction based on the proportion of respective pulse values held in a pulse value holding part with respect to the pulse value of a reference clock signal after the time for the position of one cycle elapses in a triangular wave output part. SOLUTION: When first and second input signals are inputted to a phase comparator 2, its phase difference signal is inputted to one of AND gates 3 and a reference clock signal is to the other so that the pulse rise is counted by a counter 4. In the respective outputs of integration equipments 6a and 7a, the pulse value is increased with fixed inclination for the portion of one cycle with the pulse rise timing of the reference clock signal as reference. Therefore, the output values of the integration equipments 6a and 7a in the pulse rise and fall timings of the phase difference signal are obtained. Then, a preceding stage correcting circuit 6 recognizes the time before the pulse rise of the phase signal and the time after the pulse fall of the phase signal so that the timings are correctly calculated.
